Review part RF-1027
Saturday, October 17, 2015 - Part RF-1027
I have been using this K&N product for quite a few years now. The old one was dirty so was time to put on a new one. Boy, what a difference it made. Quicker response. Faster acceleration. Higher RPMs. Would never go back to a stock filter.

My last K&N Filter RF-1027 was in my 1994 Dodge V-10 hooked up to K&N's cold air tube for 10 years. I live on dusty crushed rock roads. Filter was cleaned twice a year. Thanks for sending the replacement filter so quickly.

There were two things about the filter I wish I had known before I ordered it. The first was that the filter media to 4' tube transition was a very right angle where some of your filters have a more rounded transition to smooth the airflow, or I would assume. The second was while the inner diameter for mounting was 4in there was a narrower part. If there was a way to label these things that would be awesome because it was not completely what I was expecting.
